3D Model Evaluation System for CAD History Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3D CAD systems face challenges in effectively evaluating the quality and usability of 3D model data, particularly in managing design changes and maintaining product data quality, which can lead to unintended changes or deletions of part shapes and arrangements during data exchange, resulting in inefficiencies and resource wastage.
Innovation Solution
A 3D model evaluation system that includes a loading unit for 3D model data created by 3D CAD, a history checking unit to verify the creation history, and an evaluation unit to assess the degree of coincidence with predetermined design rules, facilitating easier evaluation and utilization of 3D model data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If 3D model data is exchanged without evaluation, then data exchange efficiency is improved, but unintended changes or deletions of part shapes and arrangements occur
Solution Approach 1:
The system performs preliminary evaluation of 3D model data before exchange by checking creation history and verifying design rules. The loading unit loads 3D model data, the history checking unit checks creation history, and the evaluation unit evaluates whether the data meets predetermined design rules, preventing quality issues before data exchange occurs
Solution Approach 2:
The system provides feedback about the quality and usability of 3D model data through evaluation results. The evaluation unit determines whether creation history meets design rules and provides this information back to users, enabling informed decisions about data exchange and maintaining quality standards
2Reliability
If detailed evaluation of 3D model data is performed, then data quality is improved, but evaluation time and complexity increase
Solution Approach 1:
The system extracts only the necessary creation history information from 3D model data for evaluation purposes. The history checking unit selectively retrieves creation history, and the evaluation unit focuses specifically on checking whether this extracted history meets predetermined design rules, avoiding unnecessary evaluation overhead
Solution Approach 2:
The 3D model data carries its own creation history information that serves as self-documentation. The history checking unit checks this embedded creation history, and the evaluation unit uses this self-contained information to automatically evaluate data quality without requiring external detailed analysis

AI summary
A 3D model evaluation system includes: a loading unit that loads 3D model data created by 3D CAD; a history checking unit that checks a creation history which is added to the 3D model data loaded by the loading unit and which is obtained in a case where the 3D model data is created by the 3D CAD; and an evaluation unit that evaluates a degree of coincidence between the creation history of the 3D model data checked by the history checking unit and a predetermined rule.
